PREPARATION OF ACETATE RAYON BY THE ACETYLATION OF VISCOSE RAYON WITH ACETIC ANHYDLIDE VAPOR

(XXI) MECHANISM OF ACETYLATION WITH SALT CATALYSTS

Abstract

The acetylation was carried out using zinc sulfate and chloride as catalysts. The mechanism is generally complicated and the reaction type varies with the concentration of catalyst, temperature of the reaction etc. Under suitable conditions the first order equation of reaction fits for the acetylation rate.
